Sample rate issue, Session was set at 44.1, forgot to change preamp to 44.1,
 
The session was created for 44.1, however I forgot to change the external clock on my preamp to 44.1 (yes, a very stupid mistake). It was at 48 through out the tracking and mixing. Now when i bounce down the tracks are slowed down about a whole step (by the ratio of 44.1 to 48). What can I do to get the tracks to bounce down at the correct speed.

-as a note through out mixing i had to face the problem of opening the sessions at 44.1 then switching the ext clock to 48 to hear them at the correct speed.

I'm totally lost on how I can get these tracks to bounce down at the correct speed. I found a lot of info for if you have your session at 48 and your preamp/ext clock at 44.1 but not the other way around like my problem.

thanks

Use a program like Goldwave to change the playback rate of the audio files to 48K, then hopefully you can relink the files once you go to open the session in LE.

I ended up doing some trial and error runs but this is how i did it if it helps any one.

-First I bounced the session in 24 bit, 44.1 multi mono.
-created a new 48 session
-switched the external clock to 44.1
-imported the audio to track
-switched the external clock back to 48
-then the audio was fine and just bounced it stereo interleaved (was my first mix to show the band)

That's an awful lot a something when you can do everything you need to do right in the Pro Tools import audio window.

Files at 48 but headers at 44.1? Import files into 48K session and uncheck the "Apply SRC" option. Files copied with new header and not sample-rate converted.
